I'm having this same problem with the backlight as I already commented in #201533. I got it working with xbacklight by changing the BACKLIGHT_CONTROL from kernel to native, whatever that means:
$ xrandr --output LVDS --set BACKLIGHT_CONTROL native -- Backlight adjustment no longer works on Thinkpad X61s https://bugs.launchpad.net/bugs/197929 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
